I am having real trouble with a file upload. The file upload works fine but i have trouble with session state. If i refer to the machine by its ip address everything works fine. However, if i go via the machines dns (eg www.blah.com) the first time ( only the first time) i upload a file iis sees the file uploaded and then starts a new session. This means @ the first attempt i upload the file, store its name and path as a session variable which is lost when the new session starts, d&#039oh. This doesn&#039t happen on any of the subsequent uploads so i&#039ve obviously done something very stupid. Any ideas would be gratefully appreciated
